<p>PURPOSE:To separate a clutch disc from a main frame quickly when the supply of the pressure oil to a cylinder chamber of a hydraulic device is cut, and prevent the dragging phenomenon of a clutch by providing an elastic member for pushing the clutch disc toward a pressure plate for energization. CONSTITUTION:A flexible plate 9 is fixed to one end of a crank shaft 6 of an engine, and a hydraulic device 12 for pressure-contacting a pressure plate 10 to a clutch disc 11 is fixed to this flexible plate 9. This hydraulic deice 12 consists of a main frame 14, a cylinder 15, a ring-shape piston 16 and a vane pump 18, and the pressure plate 10 is fixed to the side surface 16a of the piston 16. A star disc spring 60, which is formed so that an input shaft 20 is passed through a hole 60d provided in the center thereof and that multiple locking parts 60c provided in the peripheral part thereof are engaged with the engaging parts of the clutch disc 11, is provided between the main frame 14 and the clutch disc 11 to push the clutch disc 11 toward the cylinder 15 for energization.</p> |
